Session.SynchronizeDirectories() preview missing?

Hello!

I'm trying to use Session.SynchronizeDirectories but it's missing a preview flag.

How can I do preview using .NET API? I need to first synchronize using `SynchronizationMode.Both` but I need to see the changes first before I let it to proceed to do the real thing, hence I need preview first.

Thanks

Edit: I found this: https://github.com/winscp/winscp/blob/defd6cbbe3e028a2293310f70b8247365c8f2816/dotnet/Session.cs#L908 Maybe just adding a preview bool switch there will do? I can then check the SynchronizationResult and commit the changes manually by iterating the preview result list.

Edit2: I tried in my local fork of WinSCP dotnet DLL but it probably requires a bigger change than just a flag.

Thanks for your post.

I have an simple proposal for the API, new method named: Session.CompareDirectories(...) Since adding to SynchronizeDirectories is not a backwards compatible, so creating a new method is probably good idea.

It's result API could be similar as the SynchronizeResult maybe CompareResult but it would allow to commit each change one by one.
